Restore proper temperature and airflow control with the Dorman blend door actuator (P/N 604-203), the MAIN HVAC blend door actuator for a wide range of Ford trucks and vans. This electric actuator repositions the HVAC blend door on command, directing airflow through the heater core to set cabin temperature. It's a direct-fit replacement for applications including the 2000-2005 Ford Excursion, 2000-2007 Ford F-250, 1999-2007 Ford F-250 Super Duty, 2000-2007 Ford F-350, 1999-2007 Ford F-350 Super Duty, 1999-2003 Ford Windstar and more — see the Buyer's Guide tab for the full list.
If a failed blend door actuator is the cause of inconsistent heat or airflow, this replaces it.

This part cross-references / interchanges with the following part numbers:
What does the Dorman air door actuator do?
This MAIN blend door actuator is an electric motor that moves the HVAC blend door, directing airflow through the heater core to control the cabin temperature setting.
Does this Dorman hvac heater blend door actuator fit my truck?
It's a direct-fit replacement for applications such as the 2000-2005 Ford Excursion, 1999-2007 F-250/F-350 Super Duty and 1999-2003 Windstar. Check the Buyer's Guide tab for the full list.
My vehicle has more than one actuator — is this the right one?
Many vehicles use several HVAC door actuators for different positions. This is the MAIN-position part; review the application notes to confirm it matches the actuator you need to replace.
What are signs the blend door actuator may need replacing?
Signs a blend door actuator may be failing include inconsistent or wrong-temperature air, clicking or knocking behind the dash, and airflow that won't respond to temperature changes. Diagnose the cause before replacing.
Is this the Dorman heater blend door actuator 604?
Yes. This is Dorman manufacturer part number 604-203 (also written 604203), the HVAC heater blend door actuator for the listed Ford applications.
